Windows blocked the installation of a digitally unsigned driver. Uninstall the program or device that uses the driver and check the publisher's website for a digitally signed version 
of the driver.

 

Cause

This issue appears to occur when "Secure Boot" is enabled in UEFI BIOS.

Resolution

The error does not actually block the installation.  The error finishes and registers OK with the SEPC portal.

Upgrade to 22.10.0.74 of the SEPC client software.
